1. Different bank: When some banks are in the active state, the second read command (another bank) is
executed. However, in the case of a burst write, data will continue to be written until one clock before the
read command is executed. The internal auto precharge of one bank starts at the next clock of the second
command.
Write with Auto Precharge to Read command Interval (Different bank)
2. Same Bank: The consecutive read command from write with auto precharge (the same bank) is illegal. It
is necessary to separate the two commands with a bank active command.
Read command to Precharge command Interval (same bank)
